DG442DY-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG442DY-T1-E3 is a monolithic quad single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It features a normally open configuration and operates on dual supplies ranging from ±5 V to ±22 V, or a single supply up to 36 V. The device provides a typical drain-source on-resistance of 50 Ω with a maximum turn-on time of 250 ns. Built using a high-voltage silicon-gate process, it includes an epitaxial layer to prevent latchup. The component is housed in a 16-pin narrow SOIC package and supports an operating temperature range from -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E3' confirms lead-free compliance and RoHS status before procurement. Confirm the 'DY-T1' designation matches the required 16-pin narrow SOIC surface-mount package and tape-and-reel shipping format. Ensure the design accommodates the specified power dissipation limits within the target thermal environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a normally open state is required upon logic activation, distinguishing it from the DG441 variant. Validate that the 50 Ω on-resistance meets the signal integrity requirements for the specific load current. Consider the 250 ns maximum switching speed against system timing constraints and ensure the voltage ratings align with the application's supply rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG44x series of high-speed analog switches designed to upgrade legacy DG201A/DG202 sockets. The DG442 specifically offers a normally open function, contrasting with the DG441's normally closed architecture. Both share identical electrical characteristics and pinouts, allowing for functional substitution based solely on the desired default logic state.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG441DY-T1-E3 serves as a direct functional substitute if a normally closed configuration is acceptable instead of normally open.
